Ulrik CS, et al. - A prospective study was performed to investigate the relationship between body mass index (BMI) in childhood and asthma admissions (AAs) in early adulthood (age 20–45 years). From the Copenhagen School Health Records Register, 310,211 schoolchildren (born 1930–1989) were included in this investigation. It was observed that the connection between childhood BMI and AA in early adulthood was non-linear. Findings revealed that high BMI increases the risk of AA in females, while low BMI increases the risk in males.
